To all whom it may concern.

Be it known that I, CHARLES F. MoBnn, a citizen of the United States, residing at Athens, in the county of Athens and State ofOhio, have invented certain new and use- 7 construction hereinafter set forth, pointed out in my claims and illustrated in the accompanying drawing, in which,

Fig. 1 shows a perspective view' of a compiled loose leaf volume fitted out with my device;

Fig. 2 shows a perspective view of the lower cover and sheets of a loose leaf volume with my improved back ready to be fitted thereon, the dotted line showing the back in position.

Fig. -3 shows a transverse sectional View taken on the line 33'in Fig. 1.

Fig. 4 shows a pdetail view in section taken 7 on line 4.-4in Fig. 1, a .part of same being broken away.

Referring to the accompanying drawing, the reference numerals lOand 11 indicate the upper and lower covers respectively of the loose leaf volumeto be formed, the lower Q cover thereof being perforated to register with vthe perforations in the sheets to be filed. A plate 12, also perforated to register with the perforations in the sheets to be. filed, is designed to underlie the said sheets and be positionedbetween theupper surface of the lower cover and the lowermost sheet of the filer A strip of canvas, orsimilar'substance, designed to form aback for '50 that it may be doubled back overthe upper my volume on which identification marks may be placed, underlies the plate 12 and extends outwardly therefrom, its inner end extending inwardly a sufiicient distance so surface of the plate and the. end extending beyond the rear edge of the sheets to be filed,

. as shown in Fig. 2. A plate 14 also perfo-' tion with each other.

rated to register with the perforations in the sheets to be filed, is designed to rest upon the top of the uppermost sheet in the file, and the canvas back is designed to engage both the upper and lower surface ofthe said plate and be doubled thereon, as shown in Fig. 2, prior to the time that the upper plate is placed in position on the uppermost sheet.

The plate 14: is being placed in position, a U-shaped wire, or metal strip. 15, or the like, is threaded upwardly through perforations in the lower cover, the lower plate, the sheets to be filed, and the upper plate, its two ends being turned inwardly towards each other after the sheets have been pressed down into position. It is obvious this will hold the lowercover, the two plates, and the sheets, and also the back 13 in proper posi- The plate 14 is provided with a plurality wardly and designed to register with per- 'forations in the upper cover into which they project, and headed, screw caps 17 extending.

downwardly through the perforations; in the upper cover, engage the said lugs so as to hold the upper cover firmly in position.

The back 13 may, obviously, be adjusted to fit any size volume desired. I

Having thus described myv invention,

what I claim and desire to secure by Letters Patent of the'United States, is:

1. A loose leaf file comprising a' lower cover orificed to register with orifices in the sheets to be bound, aplate to be ositioned between the lower cover and t e sheets,

and a plate to be positioned above the sheets,

each of said plates orificed to register with the orifices in the lower cover and sheets, a flexible back of indeterminate length designed to be fitted to the desired volume and held in permanent position by being doubled back over the said plates, abinding means to pass through the lower cover sheets and plates andhold' them and also the flexible back. in positon, substantially as shown and described.

2. A loose leaf file comprising a lower ,cover' orifice to register with orifices in the sheets to be bound, a 'plateto be ositioned between the lower cover andthe s sets, and

a plate to be, positioned above the sheets, each of said plate orifice to register with the orifices in the lower cover and sheets, a flexible back of indetermined length designed to be fitted to the desired volume and held in permanent position by ibeingldow- 5 bled back over the said plates, a binding means to pass through the lower cover sheets and platesand hold them ande'lso the-flexistantially as shown and described. 10

In testimony whereof I have signed the foregoing specification.

CHARLES F. MoBEE.
